Abstract (en)
The invention relates to a lysing agent for use in the analysis of the blood and/or of a blood sample of a non-human mammal, said lysing agent comprising an aqueous solution, which is such that it provides, upon dilution to the final WBC/Hb dilution, a pH of between 4.0 and 7.5 for said final WBC/Hb dilution; and which contains at least one quaternary ammonium compound, in a concentration such that, upon dilution to the final WBC/Hb dilution, the total concentration of quaternary ammonium compounds in said final WBC/Hb dilution is between 1.5 and 4.5 grams per liter; and which optionally further contains one or more components for lysing agents known per se. The invention also relates to a diluent for use in the analysis of the blood and/or of a blood sample of a non-human mammal, said diluent comprising an aqueous solution: having an osmolality of between 290 and 400; having a pH of between 6.0 and 8.0; optionally at least one coagulant chosen from EDTA, citrate/citric acid and/or salicylic acid; or a combination thereof; and optionally further containing one or more components for diluents known per se. The lysing agent and diluent of the invention are suited for the analysis of blood or a blood sample of a non-human mammal - e.g. using an aperture impedance technique - and in particular for the analysis of blood or a blood sample from a cat, dog or horse.
